Patent CA-1320114-C (CA)
Title: Method and test kit for neutralization/immunoinhibition assay
Inventor: LUCAS FRANK J
IPC: G01N33/542
Filed: 1988-05-11
Granted: 1993-07-13
Abstract: ABSTRACT OF THE DISCLOSURE            Method and test kit suitable for determination of the level of a diagnostically relevant isoenzyme in a biological fluid sample. This method and test kit are based upon the determination of residual enzyme activity of a biological fluid sample subsequent to inhibition of the diagnostically relevant isoenzyme within the sample. Such neutralization/immunoinhibition of the enzyme is accomplished with a relatively impure, low avidity anti-serum which is specific for the isoenzyme. This assay is unique in that the anti-serum which is employed in the neutralization/immunoinhibition of the isoenzyme is only effective in the neutralization/immunoinhibition of from at least about 50% to up to about 85% of the original enzymatic activity of the isoenzymes within the sample, This method provides the unique ability to determine the level of diagnostically relevant isoenzyme from rate data which is inclusive of high residual enzymatic activity of the diagnostically relevant isoenzymes and other interferents, This method is suitable for determination of CK-MB levels and, thus, provides a diagnostic tool for the exclusion of acute myocardial infarction as the cause of patient distress.

Title: Application of conductive metallic film to a glass ceramic support surface
Inventor: SCHULTZ JOHN JR
IPC: C03C17/38
Filed: 1988-08-04
Granted: 1992-07-21
Abstract: APPLICATION OF CONDUCTIVE METALLIC FILM    TO A GLASS CERAMIC SUPPORT SURFACE                       ABSTRACT         A method of applying a metal film on a glass ceramic plate comprising the following steps: applying a thin layer of a metal paste comprising an metallo-organic compound preferably substantially devoid of flux material to the glass ceramic plate surface in the desired  pattern; slowly heating the plate to burn off the organic components of the paste; after cooling, covering the resultant strips of metallic  film with a thin protective layer of an organic resin material, characterized by a vaporization temperature in the normal operating temperature range to which the glass is exposed when in use.  On the first operational use of the glass the organic resin cleanly vaporizes away thereby preventing the protective coating from interfering with proper sensor operation.  This protective layer compensates for the reduced bonding of pastes having little or no flux, protecting the metal film from abrasion prior to and during assembly of the cooktop appliance.  Preferably the paste is a noble metal paste containing a substantial percentage of gold and the organic resin material is a clear acrylic resin.

Title: Production of improved rapeseed exhibiting an enhanced oleic acid content
Inventor: WONG RAYMOND S C
IPC: A01H5/10
Filed: 1988-12-29
Granted: 1995-02-07
Abstract: Improved rape plants, seeds capable of forming the same, and a novel improved vegetable oil derived from the rapeseeds are provided.  Such plants have the ability to yield a vegetable oil of increased heat stability in combination with other desirable traits.  The increased stability of the vegetable oil is attributable to the presence of an unusually high oleic acid content in the rapeseeds which has been lacking in the available rape plants of the prior art.          It has been found that the novel rape plants of the present invention reliably can be formed by mutagenesis followed by selection as described.  The vegetable oil produced by the improved rape plants of the present invention is particularly well suited for use as a frying oil wherein the increased stability at elevated temperatures is of prime importance.  In a preferred embodiment wherein the vegetable oil is used as a frying oil, the alpha-linolenic acid content concomitantly is reduced which additionally imparts an increased oxidative stability.

Abstract: PHA.40529                                    13-2-1989 ABSTRACT:          Universal remote control transmitter with simplified device identification.     A permanent non-erasable memory stores formatt-ing data and command bit patterns for a plurality of devices of different categories manufactured by different manufacturers to be controlled by the remote control transmitter incorporating the memory. To select the correct format, the user activates an enter initiate key, thereafter a key to indicate the category of the selected device, and thereafter two digits which together signify the manufacturer and model number. The keyboard output signals resulting from activation of the keys are stored in RAM in the microprocessor controlling the remote control transmitter's operation. The stored values in RAM constitute an address for the memory. Under microprocessor control, the data read out from memory is then applied to the transmitter driver circuit to cause the properly formatted device control signal to be transmitted.

Title: Data transmission method and apparatus by period shift keying (tsk)
Inventor: HAMILTON SCOTT L
IPC: H04L5/26
Filed: 1989-04-28
Granted: 1991-12-17
Abstract: DATA TRANSMISSION METHOD AND APPARATUS BY PERIOD SHIFT KEYING (TSK) ABSTRACT OF THE DISCLOSURE       Apparatus for transmitting and receiving a period shift keyed data stream comprises a data processing means such as a microproces-sor which may control the generation of the waveform as well as the determination of the bit values of an incooling signal. When the data to be transmitted comprises a plurality of data values, each data value is represented by a different predetermined frequency. Further, each data value is represented by the transmission of the predetermined frequency for a predetermined transitionary interval plus one cycle or period. One portion of the transitionary interval precedes and the remaining portion follows the one cycle. For example, the data value may be represented by a three cycle burst of frequency such that, in determining the represented data value, two cycles of transitionary interval are detected but ignored and the central cycle of the three cycle burst is timed for determining the data value by edge detection techniques. Consequently, transitionary influences caused by changes in frequency do not adversely affect data value determination.
